Neuromuscular problems in the orofacial region: aetiology and organic pathology
Abstract:
Psychological factors play a significant role in the aetiology of functional disorders of the masticatory system but the pain-dysfunction symptoms can mostly be explained with musculoskeletal tissue changes. In the jaw muscles inflammatory responses are frequently caused by muscular hyperactivity. The temporomandibular joint may be affected by many diseases of which osteoarthrosis is probably the most common. A pathologic process in the temporomandibular joint proper is often a cause of pain and dysfunction of the masticatory system, and this may be true even without radiographic evidence of structural changes.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
